I have formatted the laptop sevaral times and have updated all drivers. There are virtually no programs other than those installed by the manufacturer. I have sent the PC to the manufacturer, however they, returned it stating that no hardware issues have been found.

I was wondering if this is a hardware or software issue ?
What is the problem and how can it be fixed ?

i tried that before i sent it back to company. I formatted laptop only installed that but it didn't fix the issue. even formatting and not installing any program caused blue screens. Since i recieved it back from company the blue screen has decreased but its still there.
